1. Introduction Marine lubricants are generally formulated from highly refined mineral oils and special additive systems; a limited number of products Within the range utilize synthetic base oil (Morrison and Boyd, 1969). To ensure health and safty when using any petroleum product it is essential that: ●it is used only for the purposes for which it is intended, ●it is safety and hygiere conditions are observed. Health and safety aspects which is intended to assist the management of shipping companies to ensure that all personnel coming into direct contact With lubricants are familiar with the potential hazards associated With them,

目的探讨颈肩部疼痛及功能障碍与表面肌电图之间的关系。方法选择55例颈部或肩部疼痛的患者，采用视觉模拟量表（VAS）和颈椎功能障碍指数（NDI）评估患者颈肩疼痛和不适以及全身情况，采用表面肌电图（sEMG）评估患者颈肩部最大用力和持续打字时肌肉的功能状况，将表面肌电信号标准化处理后，比较VAS评分、NDI评分与标准化sEMG信号三者之间的相关性。按疼痛强度和功能障碍程度不同将患者分组，进一步比较其50％最大自主收缩（MVC）的波幅概率分布函数（APDF）。结果颈肩各部位的VAS评分与相应的50％MVC-APDF存在相关性，VAS评分的高低与颈肩部50％MVC-APDF大小变化一致，呈相关关系；而NDI评分与颈肩部50％MVC—APDF大小变化无相关关系；VAS评分和NDI评分之间亦存在相关性（P〈0．01）。按不同疼痛程度，将患者分为轻中度疼痛（VAS评分〈7分）和中度疼痛（VAS评分≥7分）组，2组颈肩部不同部位50％MVC—APDF比较，差异有统计学意义（P〈0．05）；按NDI评分将患者分成轻中度功能障碍（NDI评分〈25分）和重度功能障碍（NDI评分≥25分）组，2组颈肩不同部位50％MVC-APDF比较，差异无统计学意义（P〉0．05）。结论颈肩各部位的VAS评分与50％MVC-APDF之间存在相关性；颈肩疼痛程度不同，其所对应的50％MVC—APDF值亦有明显差异；NDI评分与50％MVC—APDF之间不存在相关性。

Background:To test clinically relevant factors associated with quantitative artifact-free deep capillary plexus(DCP)metrics in patients with diabetes mellitus(DM).Methods:563 eligible eyes(221 with no diabetic retinopathy[DR],135 with mild DR,130 with moderate DR,and 77 with severe DR)from 334 subjects underwent optical coherence tomography-angiography(OCT-A)with a swept-source OCT(Triton DRI-OCT,Topcon,Inc.,Tokyo,Japan).Strict criteria were applied to exclude from analysis those DCP images with artifacts and of poor quality,including projection artifacts,motion artifacts,blurriness,signal loss,B-scan segmentation error,or low-quality score.A customized MATLAB program was then used to quantify DCP morphology from the artifact-free DCP images by calculating three metrics:foveal avascular zone(FAZ),vessel density(VD),and fractal dimension(FD).Results:166(29.5%)eyes were excluded after quality control,leaving in the analysis 397 eyes(170 with no DR,101 with mild DR,90 with moderate DR,36 with severe DR)from 250 *** the multiple regression models,larger FAZ area was associated with more severe DR(β=0.687;p=0.037),shorter axial length(AL)(β=−0.171;p=0.003),thinner subfoveal choroid thickness(β=−0.122;p=0.031),and lower body mass index(BMI)(β=−0.090;p=0.047).Lower VD was associated with more severe DR(β=−0.842;p=0.001),shorter AL(β=0.107;p=0.039),and poorer visual acuity(VA)(β=−0.133;p=0.021).Lower FD was associated with more severe DR(β=−0.891;p<0.001)and with older age(β=−0.142;p=0.004).Conclusions:Quantitative artifact-free DCP metrics are associated with VA,DR severity,AL,subfoveal choroidal thickness,age,and BMI in diabetic *** effects of ocular and systemic factors should be considered for meaningful interpretations of DCP changes in DM patients.

Magnolia denudata(M. denudata) leaf litter extract(MDLLE) was tested on the response of Microcystis aeruginosa(M. aeruginosa). The inhibition of M. aeruginosa increased from 7.6% to 49.8% at 0.4 g·L^(-1) dosage while it increased from 15.7% to 77.4 % at 2.0 g·L^(-1) dosage during 15 days of incubation. The parameter variation of relative electron transport rate(rETR), maximal quantum yield(Fv/Fm ), and electron transport rates(rERTmax) indicated that photosynthesis was an important target impaired by MDLLE, including the photosynthetic center photosystem II(PSII) of M. aeruginosa which demonstrated from the rapid light curves(RLCs). The results of Chlorophyll-a(Chl-a) fluorescence, RLCs, and fluorescein diacetate(FDA) staining assays were consistent with those of growth inhibition tests. The results demonstrated that the application of MDLLE offered great potential on cyanobacterial blooms control especially at the initial stage of development. Furthermore, several kinds of volatile chemicals had been isolated in MDLLE, and the role on suppression of growth for M. aeruginosa should be further studied separately.

目的:探究中国10城市6~36月龄婴幼儿膳食多样性与自报患病情况的相关性。方法:基于2019—2020年在中国10城市开展的横断面调查的数据,通过问卷收集婴幼儿的相关人口学特征、自报患病情况及膳食多样性情况,使用卡方检验、Logistic回归、负二项回归模型分析婴幼儿膳食多样性与自报患病发生率及患病次数之间的相关性。结果:我国城市婴幼儿最低膳食多样性满足率为74.6%,婴幼儿年龄越大、家庭人均月收入越高、父亲教育程度越高其最低膳食多样性满足率更高(P<0.05)。满足最低膳食多样性的婴幼儿其呼吸系统疾病(IRR=0.76,95%CI:0.58~0.98,P=0.035)以及腹泻(IRR=0.65,95%CI:0.48~0.88,P=0.006)发生的次数更低。暂未发现婴幼儿膳食多样性与各自报疾病的发生率之间存在显著相关关系。结论:中国城市6~36月龄婴幼儿膳食多样性与呼吸系统疾病以及腹泻存在一定关联。

2′-Fucosyllactose (2’-FL) shows the potential to support intestinal health as a natural prebiotic that bridges the gap between infant formula feeding and breastfeeding. However， the effect and mechanism of 2’-FL in improving intestinal permeability are not clear. In this study， we constructed human microbiota-associated (HMA) mouse models by colonizing healthy infant feces in mice with antibiotic-depleted intestinal microbiota. The protective effect of 2’-FL on the intestinal permeability was explored using the HMA mouse models， and the combination of metagenomics was used to analyze the possible mechanisms by which the microorganisms reduced the intestinal permeability. The results showed that 2’-FL decreased the concentration of markers of intestinal permeability (enterotoxin and DAO) and increased the expression levels of tight junctions (occludin and claudin). Metagenomics revealed the enrichment of Bifidobacterium and increased the expression of glycoside hydrolases (GHs)， including GH31， GH28， and GH5. In conclusion， 2’-FL strengthened intestinal permeability function by improving microbiota composition to control the translocation of harmful substance.

目的:修订哺乳期膳食平衡指数,并评价我国十城市哺乳期妇女膳食质量,分析影响哺乳期妇女膳食质量的因素。方法:使用自设问卷和膳食频率问卷,于2019年对中国10城市863名乳母开展横断面营养健康调查。在2016年膳食平衡指数的基础上,根据2022年哺乳期妇女膳食指南调整评分标准,并评价乳母膳食质量。结果:乳母膳食摄入不平衡、不足、过量的比例分别为86.7%、85.9%、44.2%。乳母蔬菜类、水果类、奶类、大豆类及水产品类食物摄入不足,食用油和盐摄入过量严重,摄入食物多样性较低。受教育水平、收入、城市类型、体力活动水平、产后抑郁情况和是否参与孕妇学校等多种因素与乳母膳食平衡相关。结论:中国十城市乳母人群的膳食摄入不平衡主要体现为摄入不足,而摄入过量的程度相对较低。应有针对性地加强妇女产后健康教育,提高乳母膳食质量。

在过去的十年里,光网络技术的两项突破已经成为了满足业务提供商对容量的日益增长的需求的关键因素.第一项是DWDM,它可以将一根光纤分解为多个通道从而提高了现有光纤的可用带宽.第二项是通过使用像波长路由器和交叉连接系统这样的设备实现了带宽的智能化管理,这些设备能够支持具有智能配置和恢复功能的日益动态化的网络.那么下一步是什么呢?目前摆在人们面前的主要有两个挑战.其一是在需求以超乎想象的速度增长的情况下,对以数据为核心的网络不断地进行扩充,从用户接入点到城域网乃至整个长途核心网.另一个挑战是有效地创建并管理将在上述网络中运行的以数据为核心的光业务(例如,虚拟专用网上的互联网接入、内部网/外部网连接、视频会议等).
